PHILANDER PERRY, OF CHARLESTOWN, MASSAGH USETTS.

Letters Patent No. 69,017, dated iS'eptembcr 17, 1867.

COFFEE-POT.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, PIZILANDER PERRY, of Charlestown, Middlesex county, State of Massachusetts, have invented a new and improved Coffee-Pot and I do hereby declare that the following is a full and exact dcscription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in certain devices placed in the inside of the 'coffe-pot, and also an addition to the covcr by which I preserve all the aroma of the coffee-berry to flavor the cofice produced, instead of allowing it to escape into the atmosphere and go to waste.

In the drawings annexed, A and A represent the body of the cofi'ee-pot. A, the lower part, is in the shape of a truncated cone, whose top reaches to one-half the height of the coffee-pot A. The upper portion of the pot is in the form of a simple cylinder. E is the cover, with its handle F. E is a valve, door, or slide,

fastenedby a rivet (on which it moves) at one side to the cover, and moving horizontally by means of its handle, covering or uncovering at pleasure a small circular aperture in the cover E, which apcrture has across it a piece of finely perforated metal. D is the handle of the pot. G is the spent, with its stopper C, which is attached to the pot by the chain C. G is a cylindrical vessel called the tank. This has its bottom perforated with fine holes, and its sides also, to the distance of two-thirds its height, and is held with its axis vertical in the centre of the pot, at a greater or less (optional) distance from the bottom of the pot by ineans of the inverted.

shallow cup JJ, which is called the radiator. This radiator J J rests with'itsouterrixn on a projection round the interior of the chamber A", (formed by a groove round the outside of the coii'ce-pot,) and has a circular hole;

in its centre into which the tank G slides, fitting closely, and in such manner that thc tank can be at pleasure raised or lowered. H H is called the tunnel, and is formed of a tunnel, Hf, which has a handle, I, which tunnel has attached to its lower part aconduct or spout formed of an inverted tunncl, whose lower or under part has a flange which fits into the top of the tank G. The valve or door E is used to modcratc the pressure outward of the steam, and obviate the necessity of raising the cover when from nny causetoo much steam is generated.

And the operation of my combination of devices is as follows: Taking out the tank, radiator, and tunnel,

I fill the lower chamber A with water to a depth in proportion to the quantity of liquid coffee I want. Them.

by means of the -handle I, I remove the tunnel from the tank G, and place in the tank a. sufiicicnt quantity of the ground cofi ec-bcrry. I then place the tank, tunnel, and radiator in the position seen in the drawing, put:

on the cover, shutting the aperture E", and putting the stopper on the spout C. I then apply heat to the water to the point of cbullition. The steam being unable to escape by the spout, passes through the fine perforations of the tank G, through the grains of coffee, saturatin them thoroughly with the moisture, and expelling the volatile portions of them, which ascend with the steam through the tunnel II and encounters the cover E, here, being condensed by the comparatively cool metal, it falls down again in a liquid form into the tunnel,

which conducts it to the coffee-grains; through those it percolatcs, and passing through the perforations of the tank minglcs with the boiling water below. When the boiling has been carried on snilicicntly I pour through the funnel, into the lower chamber, sullicient hot water to bring the extract of coffee below to a snilicicnt stuiuuf dilution, when, all the aroma having been retained in the liquid, none passing into the atmosphere. I rcnnn'e thh cover from the spent and proceed to use the beverage.

And what I claim herein as of iny own invention, and desire/to secure by Letters Patent, is- I claim the combination and arrangement in a cofl'ec-pot of the movable perforated tank G and the tunnel H H", with the close concave radiator or diaphragm support I, when the latter is rcmovnble all substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name and aflixcd my soul this first day oi" March, 1866.
